... Though the details can differ, all stars containing less than about ten times the Sun’s mass will have the same fate. As fusion exhausts the hydrogen in their centers, their internal pressure will diminish. Gravity will pull the core in, and the core will heat up again. Hydrogen will begin “burning” ...

Calculations on space-time curvature within the Earth and Sun
... This exercise produced several expressions of relativistic curvature for solar system objects. The true diameters of the Sun and Earth are 4.1 km and 4.4 mm greater, respectively, than one would expect from applying Euclidean geometry (C = πd) to the observed surface of these bodies. These results a ...

Aquarius (constellation)
Aquarius is a constellation of the zodiac, situated between Capricornus and Pisces. Its name is Latin for ""water-carrier"" or ""cup-carrier"", and its symbol is 20px (Unicode ♒), a representation of water.Aquarius is one of the oldest of the recognized constellations along the zodiac (the sun's apparent path). It was one of the 48 constellations listed by the 2nd century AD astronomer Ptolemy, and it remains one of the 88 modern constellations. It is found in a region often called the Sea due to its profusion of constellations with watery associations such as Cetus the whale, Pisces the fish, and Eridanus the river.
